16GB DDR4 3200MHz SODIMM for Dell Latitude

This 16GB DDR4 3200MHz CL22 SODIMM is built for Dell Latitude 5420, 5421, 5430, 5511 and 5520 laptops. It runs at 1.2V with a 260-pin unbuffered non-ECC design. The module follows JEDEC PC4-25600 specifications for a warranty-safe upgrade.

Upgrading from lower capacity or slower DDR4

Replacing a smaller or slower DDR4 module with this 16GB 3200MHz stick adds headroom for multitasking and larger workloads. The jump is worth it when your current memory limits the number of applications or file sizes you can handle at once.

Check slot count and maximum supported memory

Verify how many SODIMM slots your Latitude model provides and the maximum memory the system accepts. Matching capacity, speed and manufacturer across all populated slots ensures optimal performance.

Questions about this item

Does the 260-pin SODIMM fit the Dell Latitude 5420 memory slot?

Yes, the 260-pin DDR4 SODIMM matches the slot used in the Latitude 5420, 5421, 5430, 5511 and 5520.

What is the common mistake when inserting the module into the laptop?

Not pressing firmly until the side clips click; the module must seat fully or the system will not recognise the 16 GB upgrade.

Will the non-ECC 3200 MHz stick need any firmware updates later?

No firmware is required; the JEDEC-standard DDR4 module runs at 1.2 V and is designed for the lifetime of the laptop.
